Hibernate Criteria Expression (and)

                         

In this section, you will learn to use the "and" method. This is one of the most important  method that returns the conjunctions of two expressions. You can also build the nested expressions using 'and' and 'or'. Expressions: The Hibernate Criteria API supports a rich set of comparison operators. Some standard SQL operators are =, <, ?, >, ?. 

Expression and(Criterion LHS, Criterion RHS): This method returns the conjunctions of two expressions. Both conditions are 'true' then it xecutes the query otherwise not. In this tutorial, "and" is used :

Expression.and(Expression.gt("lngInsuranceId", new Long(3), Expression.lt("IngInsuranceId", new Long(6))).

Table Name: insurance

ID insurance_name invested_amount investement_date
2 Life Insurance 25000 0000-00-00 00:00:00
1 Givan Dhara 20000  2007-07-30 17:29:05
3 Life Insurance  500 2005-10-15 00:00:00
4 Car Insurance   2500 2005-01-01 00:00:00
5 Dental Insurance 500 2004-01-01 00:00:00
Life Insurance 900 2003-01-01 00:00:00
Travel Insurance  2000  2005-02-02 00:00:00

Here is the code of the class using "and" Expression :

package roseindia.tutorial.hibernate;

import java.util.Iterator;
import java.util.List;

import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.criterion.Expression;

public class HibernateCriteriaQueryExpressionAnd {

  /**
   @param args
   */
  public static void main(String[] args) {
    // TODO Auto-generated method stub

    Session sess = null;
    try {
      SessionFactory fact = new 
Configuration
().configure().buildSessionFactory();
      sess = fact.openSession();
      Criteria crit = 
sess.createCriteria
(Insurance.class);
      crit.add(Expression.and
(Expression.gt("lngInsuranceId",new Long(3)),
 Expression.lt
("lngInsuranceId",new Long(6))));
      List list = crit.list();
      for(Iterator it = 
list.iterator
();it.hasNext();){
        Insurance ins = 
(Insurance)it.next();
        System.out.println(
"Insurance Id: " + ins.getLngInsuranceId());
        System.out.println(
"Insurance Name: "  + ins.getInsuranceName());
        System.out.println(
"Invested Amount: " + ins.getInvestementAmount());
        System.out.println(
"Investement Date: " 
+ ins.getInvestementDate());
      }
      sess.close();
    }
    catch(Exception e){
      System.out.println(e.getMessage());
    }
  }
}
